ratus for both cooling and scrubbing gas, rand second, to provide a combmatlon of arts constitutin a sin 'le iece of rela tively small apparatus, and adapted more jefliciently to perform the functions than Erelatively large separate cooling and scrubbing appliances, thus saving room or space while obtaining the advantages previously mentioned. 1

Generally stated, my invention consists in subdividing the interior of the casing of a hydraulic valve into two Chambers having communication with each other, and providing a liquid spray and a mechanical scrubbing surface in proximity with the communication between the chambers.

The 1nvent1on further comprises the 1mprovements to be presently described and finally claimed. I

The accompanying drawings illustrate one embodiment of the invention and in them Figure 1, is an elevational view principally in section.

Fig. 2 is a top or plan view principally in section, and

Fig. 8, is an elevational view, partly in section, illustrating a detail of construction.

In the drawings 1, is a casing provided with a gas inlet dip pipe 5, and adapted to contain liquid for sealing the same. The dip pipe 5, is shown as of the divided variety, but that is not essential, for an undivided dip pipe may be used. 2, is a sta tionary mechanical scrubbing surface arranged within-the casing. In the embodiment of the invention chosen for illustration this mechanical scrubbing surface consists of a series of angle-shape bars, arranged in parallel relation and projecting from the interior wall of the casing. 8, is a partition, hell or skirt sub-dividing the interior. of the easing, nto an inner and an outer chamber and adapted to dip into the liquid contained in the casing sufficiently to prevent the passage of gas under normal operating conditions. 4:, is an opening in the wall of the bell, partition or skirt and it constitutes a communication between the inner and outer chambers. This opening 1, confronts the mechanical scrubbing surface, 2. 6, is a scrubbing-jet arranged in proximity with the opening 4, and scrubbing surface 2. 7, is an off-take communicating with the outer chamber and arranged oppo site the scrubbing surface 2. 8, is a splashplate for preventing the accidental escape of liquid from the casing 1, through the oiltake 7 9, is an extension of the casing and it communicates with the liquid therein by means of the openings 13 and 14. 10, 11 and 12, constitute an overflow for maintaining an appropriate liquid level in the casing and in the extension 9. 16 and 17,

are baffle plates arranged in the outer chamber of the casing and disposed in the line ,of travel of the gas. 15, is a filling device which may be used, if required, for introducing liquid into the casing. It may he remarked that the casing 1, with its accessories and the dip pipe 5, constitute a hy draulic-valve to which is added, so as to cooperate therewith for the practice of the present invention, the parts 2, 3, 1 and 6.

In use the entire gas mixture received, is confined and discharged at relatively high velocity upon the mechanical scrubbing surface 2, in order to remove entrained matter,

and the liquid spray 6, cools the entire outgoing stream of crude gas mixture prior to its impingement upon the mechanical scrubbing surface 2. The gas is discharged normally upon or perpendicular to the corrugatedor ribbed scrubbing surface 2. The baflle plates 16 and 17, act upon the stream of gas after it leaves the scrubbing surface 2, and while it is on its way to the ofitake 7. From the foregoing description it is evident that the entire stream of gas is both cooled and scrubbed or washed in a single piece of compact apparatus, and furthermore it is evident that these operations are ef iciently performed. The relative positions of the gas inlet 4 and outlet 7 and the employment of the battle plates 16 and 17 afi'ords a very lengthy and eflicient contact of the gas with the external cooling surface of the casing 1.

It will be obvious to those skilled in the art to Which the invention relates that modificatiens may be made in details of construction arrangement With-out departing from the spirit of the invention which is not limited as to such matters or otherwise than as the prior state of the art and the ap pended claims may require.

What I claim is:

1. A gas Washer scrubber comprising thecombination of a hydraulic dip valve casing internally subdividedto constitute communieating gas receiving and discharging chambers and provided with a dip-pipe and adapted to contain liquid for sealing the dip-pipe and chambers, and a liquid spray and a stationary mechanical scrubbing surface operativ'ely arranged in proximity with the communication between the chambers, substantially as described.

2. A gas Washer-scrubber comprising. the combination of hydraulic dip valve casing internally subdivided to constitute communieating gas receiving and discharging chamhers and provided with a dip-pipe and adapted to contain li uid for seali g the dip-pipe and chambers, and a stationary mechanical scrubbing surface eperatively arranged in proximity with the communication betw'eei'i the chambers, substantially as described.

3.- A gas Washer-scrubber comprising the combination of a hydraulic dip valve casing internally subdivided to constitute communieating gas receiving and discharging chambears and provided with a dip-pipe and adapted to contain liquid for sealing the dip-pipe and chambers, a series of projections arranged in the gas discharging chamher and constituting a stationary mechanical scrubbing surface confronting the communication between the chambers, and a liquid spray in proximity With said communication and cooperating Withsaid surface.

4;. A gas Washer-scrubber" comprising the combination of a hydraulic dip valve casing internally subdivided to constitute communicating gas receiving and discharging chambers and provided With a dip=pi pe and adapted to contain liquid for sealing the dip-pipe and chambers, a liquid spray and a stationary mechanical scrubbing, surface operatively arranged in proximity With the connnunication between the chambers, and batlies arranged in the discharging chamber.

5'; A gas Washer-scrubber comprising the combination of a. casing provided With a dip pipe and adapted to contain liquid for sealing the same, a stationarymechanical scrubbing surface Within the casing, anapertured partition dipping into the liquid in the casing for confining and discharging at relatively high velocity the entire gas mixture upon said surface to remove entrained matter, and a liquid spray for cooling the entire stream of gas mixture prior to its impingement upon said surface.

6. A gas washer-scrubber comprising the combination of a casing adapted tocontain liquid and provided internally with a scrub bing surface, a skirt or bell adaptedto dip into the liquid and sub-dividing the interior of the easing into inner and outer chambers and provided with a gas opening confronting' the scrubbing surface, a dip pipe arranged in and adapted to discharge gas into the inner chamber, and a gas offtalze con nected With the outer chamber opposite the scrubbing surface, and a scrubbing jet in proximity with the scrubbing surface.
